Titan rates the RX-80 at 3600 psi (24.8 MPa) and the S-3 at 3900 psi (26.9 MPa). The S-3 is all-metal with stainless steel fluid passages, a tungsten carbide ball valve and seat, and a four-finger trigger. The RX-80 is a Red Series gun with a Comfort Grip, onboard tools, and a choice of two- or four-finger trigger.
Quick comparison
RX-80 and S-3 as Titan publishes them
| RX-80 | S-3 | |
|---|---|---|
| Maximum pressure | 3600 psi (24.8 MPa) | 3900 psi (26.9 MPa) |
| Series | Red Series | S-Series |
| Trigger | Two-finger or four-finger, depending on the configuration | Four-finger |
| Construction | Comfort Grip, Onboard Tools, Longer Life Packing Kit | All-metal stainless steel construction, stainless steel fluid passages |
| Filter | Takes the unthreaded gun filter | In-handle filter; takes the unthreaded gun filter |
| Valve | Not described by Titan | Tungsten carbide ball valve and seat |
| Swivel | 0538205 swivel on the diagram | 1/4 in. swivel |
Specs are Titan's published figures. S-3 pressure is Titan's S-Series page rating; check your gun's label and manual.
The ratings are 3600 psi against 3900 psi, so the S-3 is rated higher by a margin. That margin only helps if the rest of your system is rated for it. Never run any component above the lowest working-pressure rating in the system, including the hose, tip guard and fittings.
Construction and features
S-3
Titan calls the S-Series a work horse series. The S-3 is built of all-metal stainless steel, has stainless steel fluid passages, a filter in the handle and a four-finger trigger. The fluid valve uses a tungsten carbide ball and seat.
RX-80
The RX-80 is a Red Series gun with a Comfort Grip, Onboard Tools and what Titan calls a Longer Life Packing Kit. It is sold in several configurations: 538005 and 538007 are four-finger guns, 538006 and 538008 are two-finger, and 538009 is a four-finger gun with no tip. Titan does not call the RX-80's packing Infinity Packing, and neither do we.
Triggers and filter
If you want a two-finger trigger, the RX-80 is the one of these two that offers it. Both guns are available with four fingers. Titan lists the unthreaded gun filter for both the RX-80 and the S-3, so one filter type serves either gun. Clean the filter after each job, since a partly blocked filter causes pressure loss, pulsing and spitting.
Shared parts
The two diagrams have two part numbers in common. Everything else on them is different, so do not assume parts swap between the guns.
- 560-038 handle seal: callout 20 on the RX-80 list, callout 16 on the S-3 list.
- 651-020 tip seal: callout 10 on the RX-80 list, callout 7 on the S-3 list.
Rebuild parts
Each gun has its own repair kit on its diagram. The RX-80 uses 0538215, the RX-80 Gun Repair Kit. The S-3 uses 550-276, the Gun Repair Kit; the S-3 accessories page also lists 550-275. We do not list the contents of either kit, so open the product page or call us before you order.
On the S-3 list, the packing seal assembly is 550-264 and the diffuser is 550-277. On the RX-80 list, they are 0538210 (seal assembly) and 0538200 (diffuser, 7/8 in.).
Which to choose
- Your system's rating comes first. A gun rated above your hose and sprayer does not raise your limit.
- Trigger. Need two fingers? Choose the RX-80. Four fingers work on either.
- Materials. The S-3's construction is stainless steel with a tungsten carbide valve. If you spray a coating you are concerned about, ask the coating maker whether it is compatible with the gun's materials. We do not make coating-compatibility claims for either gun.

The Short Version
RX-80: 3600 psi (24.8 MPa), Red Series, two- or four-finger. S-3: 3900 psi (26.9 MPa), all-metal stainless with stainless fluid passages and a four-finger trigger. They share the 560-038 handle seal and 651-020 tip seal. Choose by your system's lowest rating and the trigger you want.
